+udev 147
+========
+Bugfixes.
+
+To support DEVPATH strings larger than the maximum file name length, the
+private udev database format has changed. If some software still reads the
+private files in /dev/.udev/, which it shouldn't, now it's time to fix it.
+Please do not port anything to the new format again, everything in /dev/.udev
+is and always was private to udev, and may and will change any time without
+prior notice.
+
+NAME="%k" causes a warning now. It's is and always was completely superfluous.
+It will break kernel supplied DEVNAMEs and therefore it needs to be removed
+from all rules.
+
+udev 146
+========
+Bugfixes.
+
+The udevadm trigger "--retry-failed" option, which is replaced since quite
+a while by "--type=failed" is removed.
+
+The failed tracking was not working at all for a few releases. The RUN
+option "ignore_error" is replaced by a "fail_event_on_error" option, and the
+default is not to track any failing RUN executions.
+
+New keymaps, new modem, hid2hci updated.
+
+udev 145
+========
+Fix possible crash in udevd when worker processes are busy, rules are
+changed at the same time, and workers get killed to reload the rules.
+
+udev 144
+========
+Bugfixes.
+
+Properties set with ENV{.FOO}="bar" are marked private by starting the
+name with a '.'. They will not be stored in the database, and not be
+exported with the event.
+
+Firmware files are looked up in:
+ /lib/firmware/updates/$(uname -r)
+ /lib/firmware/updates
+ /lib/firmware/$(uname -r)
+ /lib/firmware"
+now.
+
+ATA devices switched the property from ID_BUS=scsi to ID_BUS=ata.
+ata_id, instead of scsi_id, is the default tool now for ATA devices.
+
+udev 143
+========
+Bugfixes.
+
+The configure options have changed because another library needs to be
+installed in a different location. Instead of exec_prefix and udev_prefix,
+libdir, rootlibdir and libexecdir are used. The Details are explained in
+the README file.
+
+Event processes now get re-used after they handled an event. This reduces
+the number of forks and the pressure on the CPU significantly, because
+cloned event processes no longer cause page faults in the main daemon.
+After the events have settled, a few worker processes stay around for
+future events, all others get cleaned up.
+
+To be able to use signalfd(), udev depends on kernel version 2.6.25 now.
+Also inotify support is mandatory now to run udev.
+
+The format of the queue exported by the udev damon has changed. There is
+no longer a /dev/.udev/queue/ directory. The current event queue can be
+accessed with udevadm settle and libudedv.
+
+Libudev does not have the unstable API header anymore. From now on,
+incompatible changes will be handled by bumping the library major version.
+
+To build udev from the git tree gtk-doc is needed now. The tarballs will
+build without it and contain the pre-built documentation. An online copy
+is available here:
+ http://www.kernel.org/pub/linux/utils/kernel/hotplug/libudev/
+
+The tools from the udev-extras repository have been merged into the main
+udev repository. Some of the extras have larger external dependencies, and
+they can be disabled with the configure switch --disable-extras.
+
+udev 142
+========
+Bugfixes.
+
+The program vol_id and the library libvolume_id are removed from the
+repository. Libvolume_id is merged with libblkid from the util-linux-ng
+package. Persistent disk links for label and uuid depend on the
+util-linux-ng version (2.15) of blkid now. Older versions of blkid
+can not be used with udev.
+
+Libudev allows to subscribe to udev events. To prevent unwanted messages
+to be delivered, and waking up the subscribing process, a filter can be
+installed, to drop messages inside a kernel socket filter. The filters
+match on the <subsytem>:<devtype> properties of the device.
+ This is part of the ongoing effort to replace HAL, and switch current
+users over to directly use libudev.
+ Libudev is still marked as experimental, and its interface might
+eventually change if needed, but no major changes of the currently exported
+interface are expected anymore, and a first stable release should happen
+soon.
+
+A too old kernel (2.6.21) or a kernel with CONFIG_SYSFS_DEPRECATED
+is not supported since while and udevd will log an error message at
+startup. It should still be able to boot-up, but advanced rules and system
+services which depend on the information not available in the old sysfs
+format will fail to work correctly.
+
+DVB device naming is supplied by the kernel now. In case older kernels
+need to be supported, the old shell script should be added to a compat
+rules file.
+
+udev 141
+========
+Bugfixes.
+
+The processed udev events get send back to the netlink socket. Libudev
+provides access to these events. This is work-in-progress, to replace
+the DeviceKit daemon functionality directly with libudev. There are
+upcoming kernel changes to allow non-root users to subcribe to these
+events.
+
+udev 140
+========
+Bugfixes.
+
+"udevadm settle" now optionally accepts a range of events to wait for,
+instead of waiting for "all" events.
+
+udev 139
+========
+Bugfixes.
+
+The installed watch for block device metadata changes is now removed
+during event hadling, because some (broken) tools may be called from udev
+rules and (wrongly) open the device with write access. After the finished
+event handling the watch is restored.
+
+udev 138
+========
+Bugfixes.
+
+Device nodes can be watched for changes with inotify with OPTIONS="watch".
+If closed after being opened for writing, a "change" uevent will occur.
+/dev/disk/by-{label,uuid}/* symlinks will be automatically updated.
+
